Dmenu is a simple menu system for Dingux (Linux on Dingoo A320). It resembles
the original XMB-like menu comes with the stock Dingoo A320 firmware.

Theme support
-------------
Dmenu on startup reads /usr/local/dmenu/main.cfg, which contains a line to
specify the theme in the form of "Theme = <theme name>".
Dmenu reads /usr/local/dmenu/themes/<theme name>/theme.cfg to load the theme.
Check theme 'default' to find out what are the options available in theme config
file.
to main.cfg, and add below MenuItem to one of the menu,
MenuItem ThemeSelect
{
Icon = <icon file name>
Name = "Select Theme"
Executable = "!themeselect"
}
Once you select this MenuItem in Dmenu, it will display a list of themes
available and allow you to switch the theme. The theme preview shown in the
theme selection screen is theme.png in the root of the theme folder. If the
preview is not found, it will default to the notfound.png found in the
resources folder.
Due to miniSD file system corruption bug in Dingux, writing to the file system within Dmenu
can be disabled. To control this behavior set the config value as follows (in dmenu.ini):
ReadOnly = true
(You can use the keyword "yes" as same as "true")
*******************************************************************************
A word of caution, this will update main.cfg with the new theme name you have
selected. There is a possibility of file system corruption. Use it at your own
risk.
The recommended method of changing theme is manually edit main.cfg outside
Dingux, until the bug is fixed.
*******************************************************************************
Theme config file includes
--------------------------
Theme config file can include other config files. See theme.cfg in the sample
theme called 'include_sample'.
SearchPath
----------
Dmenu is able to search additional path for config files. Use SearchPath option
in main.cfg to specify the path to search. Applications can provide its own
dmenu config file (must be named dmenu.cfg) in the following format,
Menu <Menu name>
{
MenuItem <MenuItem name>
{
Icon = <Path to icon file>
Name = <Progam name>
Executable = <Path to executable>
WorkDir = <Path to work directory>
}
}
After Dmenu read this file, it will add the MenuItem into the Menu specified by
<Menu name>.
For example, with the following directory structure,
<Some Dir>
|
- App1
| |
| - dmenu.cfg
|
- App2
| |
| - dmenu.cfg
.
.
.
And "SearchDir = <Some Dir>" is specified in main.cfg, Dmenu will read all
dmenu.cfg files in subdirectories of <Some Dir>.
To specify multiple search directories, use the following format,
SearchDir = {"search dir 1", "search dir 2", etc}
In the individual dmenu.cfg files, if the icon file path is relative (i.e. the
first char is not '/'), Dmenu will treat this as relative to the directory where
this dmenu.cfg is in.
Take a look at <dmenu install dir>/sample_search_dir to see how this works.
SubMenu
-------
To add a submenu, just add a menuitem without executable and workpath, but with
SubMenuItems. For example,
MenuItem SubMenuTest
{
Icon = "res/game1.png"
Name = "SubMenuTest"
SubMenuItem SubTest1
{
Icon = "res/game2.png"
Name = "SubTest1"
Executable = "./duh"
WorkDir = "/usr/local/duh"
}
SubMenuItem SubTest2
{
Icon = "res/game2.png"
Name = "SubTest2"
Executable = "./duh"
WorkDir = "/usr/local/duh"
}
}
Once the submenu is selected, press A to open it, and press B to close. Use
up/down to select the submenu items and press A to launch.
One caveat though, dmenu.cfg included from SearchPath does not support submenu.
dmenu will print a warning and ignore the menuitem if it's a submenu.
Selector and SelectorDir
------------------------
In MenuItem and SubMenuItem, you can use Selector and SelectorDir to get into
the filelist. For example,
MenuItem foo
{
Icon = "res/emu1.png"
Name = "SomeEmulator"
Executable = "./emu"
WorkDir = "/usr/local/emulator/emu"
Selector = "true"
SelectorDir = "/usr/local/data/roms"
}
The filelist current folder is set to "SelectorDir". If the user has set
SelectorDir manually for a MenuItem (by pressing Start in the fileselector),
that value will override the MenuItem value.
Theme Selector with thumbnail
-----------------------------
In the menu, you can utilize the builtin Theme Selector menuitem.
For example,
MenuItem ThemeSelect
{
Icon = "res/star1.png"
Name = "Select Theme"
Executable = "!themeselect"
}
The code will automatically scan the themes folder and determine
the theme preview from an image file in the theme folder.
<dmenu_root>/themes/<theme_name>/theme.png is the file that will
be used to determine the theme preview. If the preview.png is not
found then resources/notfound.png is used.
Wallpaper Selector with thumbnail
---------------------------------
In Menu, you can make "built in Wallpaper Selector" menuitem.
For example,
MenuItem BackgroundSelect
{
Icon = "res/star1.png"
Name = "Select Wallpaper"
Executable = "!backgroundselect"
}
You can add your favorite wall paper to "/usr/local/dmenu/wallpapers".
WallpaperSelecter pick up all png file automatically from that folder.
FontColor Selector
------------------
In Menu, you can make "FontColor Selector" menuitem.
For example,
MenuItem FontColor
{
Icon = "res/tri4.png"
Name = "FontColor"
Executable = "!colorselect"
}
UTF-8
-----
To display UTF8 characters, font file specified in theme.cfg should contain the
necessary characters. UTF8 chars in theme.cfg name strings, and filenames in
file selector will be displayed accordingly.
Building dmenu
--------------
There are 2 makefiles in dmenu source distribution, Makefile.host and
Makefile.dingoo.
Makefile.host will build dmenu to run on host pc running linux. This is a
standard SDL application. You will need the SDL development libraries and
libconfuse to build.
Makefile.dingoo is the makefile for building dmenu to run in Dingux. You need
booboo's Dingux toolchain to build this. All the required libraries are already
included in the toolchain.
